Convert QPixmap to QByteArray
This is one way to convert "QPixmap":http://doc.qt.nokia.com/latest/qpixmap.html to "QByteArray":http://doc.qt.nokia.com/latest/qbytearray.html.
Useful when you want to store a pixmap in a database etc.
<br />QPixmap pixmap;<br />// Preparation of our QPixmap<br />QByteArray bArray;<br />QBuffer buffer( &bArray );<br />buffer.open( QIODevice::WriteOnly );<br />pixmap.save( &buffer, "PNG&quot; );<br />
Now variable bArray contains the byte array form of pixmap.
